macbook SD card info says 1/2 full but card is empty, what is going on?
I have a 1 GB PNY brand SD card. I put it into my MacBook & info says only 580mg available but the card is empty. I had some data on the card but no long needed the info so deleted everything without any change in the available space on the card. What's up? Is it Yosemite? Is it the card?
Any assistance would be greatly appreciated. Thanks in advance.
